<h1 id="一、应用层如何操控-GPIO"><a href="#一、应用层如何操控-GPIO" class="headerlink" title="一、应用层如何操控 GPIO  "></a><font size=3>一、应用层如何操控 GPIO  </font></h1><p>与 LED 设备一样， GPIO 同样也是通过 sysfs 方式进行操控，进入到&#x2F;sys&#x2F;class&#x2F;gpio 目录下，如下所示：  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240903075707130.png" alt="image-20240903075707130" style="zoom:50%;" />

<p>可以看到该目录下包含两个文件 export、 unexport 以及 5 个 gpiochipX（X 等于 0、 32、 64、 96、 128）命名的文件夹。  接下来我们就来学习一下这些的用途。</p>
<h2 id="1-gpiochipX"><a href="#1-gpiochipX" class="headerlink" title="1. gpiochipX"></a><font size=3>1. gpiochipX</font></h2><p>当前 SoC 所包含的 GPIO 控制器，我们知道 I.MX6UL&#x2F;I.MX6ULL 一共包含了 5 个 GPIO控制器，分别为 GPIO1、 GPIO2、GPIO3、 GPIO4、 GPIO5，在这里分别对应 gpiochip0、 gpiochip32、gpiochip64、 gpiochip96、 gpiochip128 这 5 个文件夹， 每一个gpiochipX 文件夹用来管理一组 GPIO。随便进入到其中某个目录下，可以看到这些目录下包含了如下文件：  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240903075851275.png" alt="image-20240903075851275" style="zoom:50%;" />

<p>在这个目录我们主要关注的是 base、 label、 ngpio 这三个属性文件，这三个属性文件均是只读、不可写。</p>
<ul>
<li>base</li>
</ul>
<p>与 gpiochipX 中的 X 相同，表示该控制器所管理的这组 GPIO 引脚中最小的编号。每一个 GPIO引脚都会有一个对应的编号， Linux 下通过这个编号来操控对应的 GPIO 引脚。  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904073824362.png" alt="image-20240904073824362" style="zoom:50%;" />

<ul>
<li>label</li>
</ul>
<p>该组 GPIO 对应的标签，也就是名字。  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904073934293.png" alt="image-20240904073934293" style="zoom:50%;" />

<ul>
<li>ngpio</li>
</ul>
<p> 该控制器所管理的 GPIO 引脚的数量（所以引脚编号范围是： base ~ base+ngpio-1） 。  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904074057803.png" alt="image-20240904074057803" style="zoom:50%;" />

<p>对于给定的一个 GPIO 引脚，如何计算它在 sysfs 中对应的编号呢？其实非常简单，例如给定一个 GPIO引脚为 GPIO4_IO16，那它对应的编号是多少呢？首先我们要确定 GPIO4 对应于 gpiochip96，该组 GPIO 引脚的最小编号是 96（对应于 GPIO4_IO0），所以 GPIO4_IO16 对应的编号自然是 96 + 16 &#x3D; 112；同理GPIO3_IO20 对应的编号是 64 + 20 &#x3D; 84。</p>
<h2 id="2-export"><a href="#2-export" class="headerlink" title="2. export"></a><font size=3>2. export</font></h2><p>用于将指定编号的 GPIO 引脚导出。 <strong>在使用 GPIO 引脚之前，需要将其导出，导出成功之后才能使用它</strong>。 注意 export 文件是<strong>只写文件，不能读取</strong>，将一个指定的编号写入到 export 文件中即可将对应的 GPIO 引脚导出，如：</p>
<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">echo 0 &gt; export # 导出编号为 0 的 GPIO 引脚（对于 I.MX6UL/I.MX6ULL 来说，也就是GPIO1_IO0）</span><br></pre></td></tr></table></figure>

<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904074600278.png" alt="image-20240904074600278" style="zoom:50%;" />

<p>导出成功之后会发现在&#x2F;sys&#x2F;class&#x2F;gpio 目录下生成了一个名为 gpio0 的文件夹（gpioX， X 表示对应的编号），如下图所示。这个文件夹就是导出来的 GPIO 引脚对应的文件夹，用于管理、控制该 GPIO 引脚，稍后再学习。  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904074750867.png" alt="image-20240904074750867" style="zoom:50%;" />

<p>控制 GPIO 引脚主要是通过 export 导出之后所生成的 gpioX（X 表示对应的编号）文件夹，在该文件夹目录下存在一些属性文件可用于控制 GPIO<br>引脚的输入、输出以及输出的电平状态等。  </p>
<blockquote>
<p>需要注意的是，并不是所有 GPIO 引脚都可以成功导出， 如果对应的 GPIO 已经在内核中被使用了， 那便无法成功导出，打印如下信息：  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904075130193.png" alt="image-20240904075130193" style="zoom:50%;" />

<p>这也就是意味着该引脚已经被内核使用了，例如某个驱动使用了该引脚，那么将无法导出成功。  </p>
</blockquote>
<h2 id="3-unexport"><a href="#3-unexport" class="headerlink" title="3. unexport"></a><font size=3>3. unexport</font></h2><p>将导出的 GPIO 引脚删除。当使用完 GPIO 引脚之后，我们需要将导出的引脚删除，同 样该文件也是只写文件、不可读，例如：</p>
<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">echo 0 &gt; unexport # 删除导出的编号为 0 的 GPIO 引脚</span><br></pre></td></tr></table></figure>

<p>删除成功之后，之前生成的 gpio0 文件夹就会消失：</p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904074926762.png" alt="image-20240904074926762" style="zoom:50%;" />

<h2 id="4-gpioX"><a href="#4-gpioX" class="headerlink" title="4. gpioX"></a><font size=3>4. gpioX</font></h2><p>将指定的编号写入到 export 文件中，可以导出指定编号的 GPIO 引脚，导出成功之后会在&#x2F;sys&#x2F;class&#x2F;gpio目录下生成对应的 gpioX（X 表示 GPIO 的编号）文件夹，以前面所生成的 gpio0 为例，进入到 gpio0 目录，该目录下的文件如下所示：  </p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904075323361.png" alt="image-20240904075323361" style="zoom:50%;" />

<p>我们主要关心的文件是 active_low、 direction、 edge 以及 value 这四个属性文件，接下来分别学习这四个属性文件的作用：  </p>
<ul>
<li>direction</li>
</ul>
<p>配置 GPIO 引脚为输入或输出模式。该文件可读、可写，读表示查看 GPIO 当前是输入还是输出模式，写表示将 GPIO 配置为输入或输出模式；读取或写入操作可取的值为”out”（输出模式）和”in”（输入模式），如下所示：</p>
<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904075525666.png" alt="image-20240904075525666" style="zoom:50%;" />

<ul>
<li>value</li>
</ul>
<p>在 GPIO 配置为输出模式下，向 value 文件写入”0”控制 GPIO 引脚输出低电平，写入”1”则控制 GPIO 引脚输出高电平。在输入模式下，读取 value 文件获取 GPIO 引脚当前的输入电平状态。例如：</p>
<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br></pre></td><td class="code"><pre><span class="line"><span class="meta prompt_"># </span><span class="language-bash">获取 GPIO 引脚的输入电平状态</span></span><br><span class="line">echo &quot;in&quot; &gt; direction</span><br><span class="line">cat value</span><br><span class="line"><span class="meta prompt_"># </span><span class="language-bash">控制 GPIO 引脚输出高电平</span></span><br><span class="line">echo &quot;out&quot; &gt; direction</span><br><span class="line">echo &quot;1&quot; &gt; value</span><br></pre></td></tr></table></figure>

<img data-src="https://fanhua-picture.oss-cn-hangzhou.aliyuncs.com/01%E5%B5%8C%E5%85%A5%E5%BC%8F%E5%BC%80%E5%8F%91/02IMX6ULL%E5%B9%B3%E5%8F%B0/LV03-%E5%BA%94%E7%94%A8%E5%BC%80%E5%8F%91/LV15-02-GPIO%E6%8E%A7%E5%88%B6-01-%E5%9F%BA%E7%A1%80%E7%9F%A5%E8%AF%86/img/image-20240904075727400.png" alt="image-20240904075727400" style="zoom:50%;" />

<ul>
<li>active_low</li>
</ul>
<p>这个属性文件用于控制极性， 可读可写，默认情况下为 0，如：</p>
<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br></pre></td><td class="code"><pre><span class="line"><span class="meta prompt_"># </span><span class="language-bash">active_low 等于 0 时</span></span><br><span class="line">echo &quot;0&quot; &gt; active_low</span><br><span class="line">echo &quot;out&quot; &gt; direction</span><br><span class="line">echo &quot;1&quot; &gt; value       # 输出高</span><br><span class="line">echo &quot;0&quot; &gt; value       # 输出低</span><br><span class="line"><span class="meta prompt_"></span></span><br><span class="line"><span class="meta prompt_"># </span><span class="language-bash">active_low 等于 1 时</span></span><br><span class="line"><span class="meta prompt_">$ </span><span class="language-bash"><span class="built_in">echo</span> <span class="string">&quot;1&quot;</span> &gt; active_low</span></span><br><span class="line"><span class="meta prompt_">$ </span><span class="language-bash"><span class="built_in">echo</span> <span class="string">&quot;out&quot;</span> &gt; direction</span></span><br><span class="line"><span class="meta prompt_">$ </span><span class="language-bash"><span class="built_in">echo</span> <span class="string">&quot;1&quot;</span> &gt; value     <span class="comment"># 输出低</span></span></span><br><span class="line"><span class="meta prompt_">$ </span><span class="language-bash"><span class="built_in">echo</span> <span class="string">&quot;0&quot;</span> &gt; value     <span class="comment"># 输出高</span></span></span><br></pre></td></tr></table></figure>

<p>由此看出， active_low 的作用已经非常明显了， 对于输入模式来说也同样适用。</p>
<ul>
<li>edge</li>

<p>控制中断的触发模式，该文件可读可写。 在配置 GPIO 引脚的中断触发模式之前，需将其设置为输入模式：</p>
<figure class="highlight shell"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">echo &quot;none&quot; &gt; edge      # 非中断引脚</span><br><span class="line">echo &quot;rising&quot; &gt; edge    # 上升沿触发</span><br><span class="line">echo &quot;falling&quot; &gt; edge   # 下降沿触发</span><br><span class="line">echo &quot;both&quot; &gt; edge      # 边沿触发</span><br></pre></td></tr></table></figure>

<p>当引脚被配置为中断后可以使用 poll()函数监听引脚的电平状态变化，在后面的示例中将进行学习。  </p>
